IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.This study explores fault diagnosis methods for PWM inverters in a wind energy conversion system using a doubly fed induction generator. Two intelligent diagnostic techniques, fuzzy resonant logic and artificial neural networks, are proposed. The fuzzy logic method monitors inverter faults in real time, whereas the neural network method uses 3D feature
